Korean J. Met. Mater. 2020;58(12):863-874.   Published online 2020 Dec 4
DOI: https://doi.org/10.3365/KJMM.2020.58.12.863

In this study, the effects of electrode surface design on the resistance spot weldability and degradation of the electrode following resistance spot welding (RSW) of aluminum 6014-T4 alloy were investigated. A new patterning method that can be produced through repetitive pressurization was applied to the electrode, producing a lattice-like pattern..... More

Korean J. Met. Mater. 2020;58(2):125-130.   Published online 2020 Jan 8
DOI: https://doi.org/10.3365/KJMM.2020.58.2.125

As global regulations of CO2 emissions and fuel consumption efficiency become more strict, the automotive powertrain system has become more compact with lower lubrication viscosity. With the current trends in powertrain system improvement, the operating conditions of powertrain components such as gears are becoming more severe. As a result, it..... More
